Abstract
A nanometre-class cerium oxide powder is prepared through reaction between Ce-ion solution and alkaline solution under the existance of surfactant and normal temp. and pressure. Its advantages are fine and uniform granularity (20-50 nm), normal temp. and normal pressure reaction and low cost.
Description
Technical field
The present invention relates to the manufacture method of nano material, especially the manufacture method of nano-cerium oxide.
Background technology
Nano material is the novel material that development in recent years is got up, demonstrate purposes and special excellent effect widely in each field, particularly consumption is big aspect special glass, and at present, the vehicle glass of America and Japan all adds the radiation that cerium oxide is used for antiultraviolet, infrared rays and other ray.Because technology limitation, the cerium oxide particles granularity of making can't reach nano level at present, does not far reach the production scientific research requirements.Application number is the manufacture method that 99114908 Chinese invention patent application discloses a kind of nanometer cobalt oxide, it is characterized in that in chemical precipitation method, introducing tensio-active agent, the cobalt oxide granularity that produces reaches 5～60nm, but this method will be carried out in heating condition, thereby the production unit requirement is high, and cost improves greatly.
Summary of the invention
Purpose of the present invention will provide a kind of working condition requirement simple exactly, the little and manufacture method of uniform nano-cerium oxide of product granularity.
For reaching above-mentioned purpose, the method that the present invention makes nano-cerium oxide is as follows:
A, contain the preparation of Industrial intermediates solution or other aqueous solution that contains cerium ion of cerium ion;
The preparation of B, basic solution;
C, cerium ion solution and basic solution react under the condition of introducing tensio-active agent, and reaction is carried out at normal temperatures and pressures;
The washing of D, resultant, oven dry;
In the aforesaid method, described basic solution be in sodium hydroxide, potassium hydroxide, sodium oxalate, yellow soda ash or the ammoniacal liquor any.
Described tensio-active agent is at least a in Sodium dodecylbenzene sulfonate, stearic acid oxygen Vinyl Ether series, alkylphenol polyoxyethylene class (OP series), fatty acid loss water sorbit ester class (Tween series), polyvinyl alcohol, silicone oil, the polyacrylamide, consumption be cerium in the raw material weight percent 0.1～15%.
Adopt manufacture method of the present invention, the particle diameter of cerium oxide reaches 20～50nm, and granularity is tiny evenly; Reaction is carried out at normal temperatures and pressures, and production unit requires simple.
